A few more questions:

2. Is removing the exhaust fan at the back really that helpful?
3. I'm running my HR-02 passively, would this change anything.
4. Is this what I should be looking for in a fan filter or does it matter?
5. Fan controllers. Useful? Worth it? What should I look for in a fan controller?

Try blocking the rear top fan and with the rear fan as intake. Who knows what temps you'll get?

To really work well your exhaust fan must remove all of the air your intake fans put in. Otherwise you increase your pressure as your airflow slows down to what your exhaust fan can manage.

Of course, if you leave your grill in you will need your exhaust fan to overcome the grill's resistance. This will add to your noise as well.

Running a good heatsink passively means quieter running, but you will need good case airflow.

Fan controllers are good for case fans. But if you use PWM case fans your mb can control them (up to 2 Amps total) through the cpu fan header. Or you can hook them up through an Akasa PWM splitter. That way your case fans will increase when your cpu temp goes up and blow more air as needed through your passive heatsink, and out the back.

Listen to Ehume. His advice/thread's helped drop my temps alot and i'm still not done yet. I advise reading EVERY clicky in his sig. More info in those threds than you could imagin!!
The one thing i will say is that fan controller's are very nice to have! i use the Rheosmart on my rig and LOVE it. there are cheaper ones out there, I perfer sunbeam controllers but that's me. check out the rheobus for a realy nice cheap controller, 15 bucks at local microcenter. With both of those controller's you can hook up more than one fan per channel with a Y cable. So far I had 2xSan Ace1011's +6 other random 120mm fans on ONE channle, worked perfect on my rheosmart:P Smart feature is pretty nice for keeping noise down.

Just ordered a couple of fan filters. Given how dry and dusty this place is, I'm not gonna think about turning those fans around until they come in. As soon as they do, I'll be going crazy with fan arrangements. I'm hoping they don't cut airflow too much.

And I did read through all those clickys last night. Wondering why the TY-140 didn't show up in that first one. But maybe I'm just illiterate. It happens.

What I really want is to get my rig as silent as possible without going water. I can see removing the 120mm exhaust helping with noise, and if it drops cooling even better. Need to find out what I can do with these crossfire 6850s though. I doubt there's good passive cooling for VGAs.

I know that there are some cooler's. I hate to say it, but with a dual GPU set up you kinda have to take some noise with your eyecandy. A more ear friendly set up would invlolve only a single GPU I would imagine(unless water is used). I would first set some custom fan profiles with stock coolers.
Open a temp/fan speed moniter that will work for your GPU's and take note's as to what the temps are when your doing all the stuff you do. With that data you can custom make a fan profile. That way you can at least be incontroll of when your fan kicks on high..most stock fan profiles suck anyhow.

Yeah, I'm using custom fan profiles. I'll still have to tinker with it more for when it's completely idle. What I really dislike about this setup is how much it's raised my CPU temps. Although I really should've seen that one coming. Apparently TY-140s are really quiet, might not hear it and it helps a lot with cooling. I dunno, having a passive heatsink just seems too awesome.

Powercolor has updated their announcement of a passive 6850:

PowerColor-Gets-Ready-to-Release-the-Passively-Cooled-SCS3-Radeon-HD-6850-2.jpg

I wish they had run the fins lengthwise to take advantage of front-to-back airflow in a case. Oh well.

Hey ehume you mean the 2 fans on the top put front to intake and the top rear to be block off ? But isn't 2 Intake better ? :0 I dun really understand the theory of the airflow . Haha sorry for
My noob questions .

Yes, he is suggesting blocking the second intake area. I'm going to be looking into what exactly what happens when I do this in my rig. It might just run differently depending on case/cpu cooler. Also, I'd say it definitely makes sense to block it off than leave it open and fanless.

As for the passive Powercolor. I'm not going to buy two more 6850s to replace the ones I've already got just because of that. Don't have that much cash to blow on my rig.

Oh ok I will try that . By the way how to install one fan infront of the psu ? Like make if blow upward my case it's a lancool pc63 knight series .

Yeah. I figured not. Heh. But it's one heck of a gpu to put on a passive vidcard.
